Alright, I was plan on doing this yesterday but to get it over with and to fast track to adding in the Lostbelt 3 Archives(as I'm still in a ridiculous rush to finish this, 3 and start 4 before LB5.2 happens in March...)
The Life, World and Culture of the Scandinavian Lostbelt:
(Yes, I'll try and add more of these types of maps later, give me time...)
The Hierarchy of the Lostbelt:
(Video
Here)
Da Vinci goes over the totem pole of the Lostbelt creatures here and humanity as a whole in this lost era with Humanity at the absolute bottom and barely any other creatures even LIVING in the Lostbelt.
The Giants:
(Video of First Encounter
Here)
Here, we see that they are 5 meters tall(Although considering from Golem Keter Malkuth, the 4th Anniversary
PV and how Napoleon speaks of Muspels, they aren't just limited to 5 meters tall like the rest of the monsters in FGO). 5 Meters = 16 Feet
Fate/Apocrypha material - Encyclopedia: Royal Crown, the Light of Wisdom [Noble Phantasm], p.166
[T] Royal Crown, the Light of Wisdom [Noble Phantasm]
Golem Keter Malkuth. The Noble Phantasm of Caster of Black, Avicebron. It is not something that he created while he was alive; rather, it is his unfulfilled dream that was turned into a Noble Phantasm. It is an imitation of the “first human Adam”, a Reality Marble which has been given life of its own.
Just by stepping on the ground, it is endlessly supplied with prana, and at the same time it encroaches on the surrounding land and turns it into “Eden”.
Its full height was fifteen meters at the time of its birth, but this is only the measurement of “when it was born”. As the span of Eden expands, the giant’s size will change and multiple, until it finally exceeds a thousand meters. It is said that “a fifteen-meter-sized giant could be easily defeated by even a Servant with average C rank stats, but as expected, one at the size of a thousand meters would be impossible to kill without a group of first-rate Servants. And, incidentally, the stomachs of the people tasked with covering up it all up would die.
The reason Jeanne and the others were so frantic against the giant when it was still fifteen meters tall is because they could tell that the speed of its growth was extraordinary, and if their response had been even a bit slower, the giant would have grown to thirty meters and displayed even harsher resistance.
Here, they used to live in the Scandaniva region and potentially around Sweden, Norway and Denmark(or that would be where the Scandanivan Age of the Gods ended up becoming after it's destruction).
Here, Holmes seems especially steamed that Giants was thrown at us so soon meaning that they are thus a major threat.
Here, In the FGO 4th Anniversary PV, we do see Giants(Muspels) as tall, if not taller than Mountains though meaning.
Here(Video), Napoleon does bring up how he usually takes down Giants in the Lostbelt.
Here, Napoleon believes that Giants have an extrasensory organ that allows them to see Heat Signatures or a Sixth Sense due to the Masks they wear covering their nose and faces.
Here, Da Vinci Lily confirms that the Giants are Biological Heat Seekers and goes after anything "warm"
Here, They are also capable of infusing Mystics into whatever they touch, being able to damage the Bounded Field of the Shadow Border.
Muspels:
Here, Muspels are seen as the strongest type of Giant, as well as being seen as such a threat that even the gods keep them supervised at all times.
Here, They have enough intelligence to use their own as shields as shown in this scene.
Ice Beasts...
Here, Da Vinci notes that while they are stronger than humans, but as the Giants' pets, they have no real intelligence(obviously)
I won't include the Tree of Emptiness Seeds either since they aren't a part of the Lostbelt culture for obvious reasons.
Humans:
Basically... Da Vinci isn't wrong when the Humans in the 2nd Lostbelt is seen as the lowest in the Totem Pole...
Here, Gerda nor anyone else has ever heard of the concept of Parents or even the elderly(they are seen as a legend)
Here, If you have a child, then you can stick around until you are 25, if you don't have a child by 15, then you equally have to leave.
Here, By how Gerda ultimately states her fate in such a manner of fact tone and treating it as no problem on many occasions, it's shown they literally cannot think of any other way to live past this(When Mash defeats the Envoy and Napoleon clears out the rest, the sheer cluelessness of what to do next past wait next year proves it)
Here, Once the "Ordained Day" arrives, anyone who ultimately fits the above requirements have to leave through the Gate guarding the villages which is meant only to leave while being escorted by an Envoy.
Miscellaneous because of course...
Here, Each Village is protected by a Bounded Field centering on the large Gate.
Here, It's designed to keep the Giants, Ice Beasts and anything involving Magecraft out. Even Mash felt some pressure after stepping into the Village and believes it's connected to the Snow
Here, they do ultimately point out the "Sun"(Surtr's Prison and the connection to his true body Muspelheim) is WAY too big to be a normal Sun and would otherwise be a Red Giant
Here, Holmes states if it was true in any context, the whole area would be a scorching desert and while Mash would survive it, Ritsuka wouldn't.
I sadly can't really use anything from Sitonai because while she does have some basic feats(Like inadvertently messing up Ritsuka's body trying to establish contact too fast and why Scathath-Skadi locked her up), she really does nothing of note even compared to those in Lostbelt 1 or otherwise.
To clarify this further: It's not that Sitonai in the story or the character is helpless, she's a Dragon Slayer so by that logic, she's still a powerhouse and a High Servant so she's very powerful... the problem is that there's no real reason to list her feats because nothing she does is truly impressive for a list like this.
So that leaves one left... you guys know the one:
The beginning of Loptr Laejrn
here(Video)
Here, Surtr's destination is Lake Vanern(in our equivalent area) to show Ophelia how the "richest" parts of the Lostbelt(Villages, Animals, Plant Life) will burn to ash with his Noble Phantasm.
Here(Video), Ophelia states the Sword is superheated over 4 million Celsius even before he does the TNR and compares the speed of it's descent to a shooting star.
Here(Video), Gerda confuses it for the Sun due to how bright it is(which actually makes sense for Fire that heated up).
Heracles(It's him, considering how he virtually appears everywhere Sitonai does, it's him 100%) Blocking Loptr Laegjrn
here(Video)
Here, Sitonai explicitly states to take it all, including the Magical Energy to produce it(Meaning he truly did block it on his own even before he got assistance)
Here, Sitonai even states the recoil of Heracles blocking Loptr Laejrn to her is absolutely intense and she can't keep it up for long(again all but stating he was blocking it without assistance).
Here, Sitonai asks for backup from Scathath Skadi and Ortlinde and THEN they give backup(This also makes sense as they was in the Shadow Border with you meaning there was no way they could have gotten there any faster without you guys being there either).
I could bring up how different LB2's Scandaniva is from real life Scandaniva... but that's a matter of course.
Later!
